Good Afternoon,
We have a 2 node Hyper-V cluster with 4 VMs running (we are using Starwind VSAN free). We have 2 ISCSI luns with 2 VMs on each. The luns are roughly 35% used. It has all been working fine for months and then yesterday afternoon we started having problems with 2 of the VMs suddenly becoming unresponsive and the hosts have disk bad block errors in the event logs. We have narrowed it down to the VMs that are unresponsive are both on one CSV. If I move a problem VM to the other CSV then it becomes responsive again.

It all shows as connected in ISCI and the CSVs are synchronised according to the event logs.

I'm new to the Starwind VSAN and struggling to find whats wrong is there any where I can look to troubleshoot this? Or can anyone offer advice/assistance?



Thanks in advance.
